Hemoagglutination inhibiting antibody of Japanese Encephalitis In the sera of inpatients of a hospital in Kurashiki City and that in the sera of an upper secandary school pupils in Kurashiki City (EpidemiologIcal Study on Japanese Encephalitis, 68)

The rale of inpatients and high school pupils in Kurashiki City having value under 10 in HI reaclion was 11.4% and 15.2% respectively, suggesting that about one seventh of inhabitants have relatively a few HI antibody just before the season of outbreak of Japanese Encephalitis in Southern part of Okayama Prefecture

Association of explanatory histological findings and urinary protein and serum creatinine levels at renal biopsy in lupus nephritis: a cross-sectional study

Background The aim of the present study was to evaluate the association between the histology of active and chronic lesions and urinary protein and serum creatinine (SCr) levels, as common clinical endpoints in clinical trials for lupus nephritis (LN). Methods In total, 119 patients diagnosed with LN class III, IV, and V, as defined by the International Society of Nephrology/Renal Pathology Society, between 1990 and 2015, were enrolled in the present study. Multiple regression analysis was performed to explore semi-quantitative histological variables associated with urinary protein and SCr levels. Results The mean age of the enrolled patients was 45 years, and 79% were female. The mean SCr and mean urinary protein levels at the time of renal biopsy were 0.87 mg/dl and 3.00 g/gCr, respectively. Class IV (71%) was the most common type of LN followed by class III (17%), and class V (13%). Multicollinearity was confirmed between monocellular infiltration (variance inflation factor [VIF] = 10.22) and interstitial fibrosis (VIF = 10.29), and between karyorrhexis (VIF = 4.14) and fibrinoid necrosis (VIF = 4.29). Fibrinoid necrosis and monocellular infiltration were subsequently excluded, and multiple regression analysis revealed that only the urinary protein level was correlated with wire loop lesions (β-coefficient [β]: 1.09 and confidence interval [CI]: 0.35 to 1.83), and that the SCr level was correlated with glomerular sclerosis (β: 1.08 and CI: 0.43 to 1.74). Conclusion As urinary protein and SCr levels were not quantitatively associated with active lesions, they may not accurately reflect the response to remission induction therapy in patients with LN

Alternative to Rituximab Therapy for a Patient with Ankylosing Spondylitis Who Was Unable to Continue Anti-TNF Therapy

We herein present a case of a 38-year-old man who had bamboo spine and severe sacroiliitis and who was diagnosed with ankylosing spondylitis (AS). Infliximab (IFX) markedly improved the axial symptom but was discontinued due to the side effect of peripheral neuropathy. Switching from IFX to etanercept worsened the side effect. Rituximab (RTX) administration elicited a good response without side effects. RTX might be a suitable option for AS therapy when TNF inhibitors are difficult to use

Spectroscopy of Heavy Mesons Expanded in 1/m_Q

Operating just once with the naive Foldy-Wouthuysen-Tani transformation on the relativistic Fermi-Yang equation for $Q\bar q$ bound states described by the semi-relativistic Hamiltonian which includes Coulomb-like as well as confining scalar potentials, we have calculated heavy meson mass spectra of D and B together with higher spin states. Based on the formulation recently proposed, their masses and wave functions are expanded up to the second order in $1/m_Q$ with a heavy quark mass $m_Q$ and the lowest order equation is examined carefully to obtain a complete set of eigenfunctions for the Schr\"odinger equation. Heavy quark effective theory parameters, $\bar\Lambda$, $\lambda_1$, and $\lambda_2$, are also determined at the first and second order in $1/m_Q$.Comment: 49 pages, 5 epsf figure

Seasonal level of hemoagglutinin inhibitinlt and its 2-mercaptoethanol sensitive antibody in the sera of swine (Epidemiological Study on Japanese Encephalitis, 67)

Seasonal level of hemoagglutinin inhibiting and its 2 -mercaptoethanol sensitive antibody in the sera of swine were researched and the following results were obtained. 1. The positive rate of hemoagglutination inhibit reaction (HI reaction) on swine showed 100% at maximum in the middle of September. 1980. The positive rate of 2-ME sensitive antibody showed the titer of over 1 : 40 with all swine examined in the middle of August, 1980. 2. The positive rate of HI reaction of inhabitants at Mukaiyama in Kurashiki City was 76.0% (on 8th in July, 1980) indicating the rather big decrease being compared with annual value of 90.6%, in 1976. Date indicated that increase In JE virus in swine as source of infection thought to be a vector of JE, caused a genuine case of JE, in 1980, as described below. 3. Higher positive rate of HI reaction and 2-ME sensitive positive rate of swine were observed in 1980. 4. One patient who suffered from JE was found In Kurashiki City in 1980. 5. Henceforth and continuously, Japanese Encephalitis should be investigated, above all on its occurance order with the number or Ct or the positive rate of hemoagglutination inhibit reaction in inhahitants and swine, etc. considering that J.E. has a high lethality rate and often leaves the terrible J. E. residue to patients

Amplified EPOR/JAK2 Genes Define a Unique Subtype of Acute Erythroid Leukemia

ゲノム解析から急性赤白血病の変異プロファイルと治療標的を解明 --特定の遺伝子変異群の組み合わせと、特徴となる遺伝子の増幅が鍵--. 京都大学プレスリリース. 2022-08-05.Acute erythroid leukemia (AEL) is a unique subtype of acute myeloid leukemia characterized by prominent erythroid proliferation whose molecular basis is poorly understood. To elucidate the underlying mechanism of erythroid proliferation, we analyzed 121 AEL using whole-genome/exome and/or targeted-capture sequencing, together with transcriptome analysis of 21 AEL samples. Combining publicly available sequencing data, we found a high frequency of gains/amplifications involving EPOR/JAK2 in TP53-mutated cases, particularly those having >80% erythroblasts designated as pure erythroid leukemia (10/13). These cases were frequently accompanied by gains/amplifications of ERG/ETS2 and associated with a very poor prognosis, even compared with other TP53-mutated AEL. In addition to activation of the STAT5 pathway, a common feature across all AEL cases, these AEL cases exhibited enhanced cell proliferation and heme metabolism and often showed high sensitivity to ruxolitinib in vitro and in xenograft models, highlighting a potential role of JAK2 inhibition in therapeutics of AEL
